IMPROVEMENT lN SEATS OR BENCHES.

Specification forming part of Letters Patent No. 222,403, dated December 9, 1879 application filed July 3; 1879.

To all whom it may concern! Be it known that I, RICHARD W. HOW, of the city of Brooklyn, in the county of Kings and State of New York, have invented certain new and usefulImprovements inSeats or Benches; and I do hereby declare that the following is a full and'exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.

In the accompanyingdrawings, Figure 1 represents an end elevation of my improved seat. .Fig. 2 represents a front elevation of the same. Fig. 3 represents a vertical'crossseat, made of about the usual contour, but

with lug-like portions a a to support the metal seat-sustaining bars B B, and with tapering projections O O on each of the backposts, for the attachment of the wooden backbars. The Wooden back-bars D E,two or more in number, have each two metallic shoe-pieces, 1) b that fit onto the projections O (J in a dovetailing manner, asclearlyillnstrated, (see Figs. 2 and 6,) so that when the parts are put together the shoe-pieces b b interlock with or drive onto the projections C and couple the wooden bars DE tolthefback posts orportions A of the end frames with sufficient' security and permanency for use, while at the same time these parts may be separated, when desired, for storage, &c., by simply driving apart the said shoe-pieces and the projections on which they fit.

Each of the wooden seat-bars F is permanently fastened, near its ends, to each of the removable metal bars B B by screws in about the usual manner of fastening such seat-bars to the irremovable metal-bar portion of the old-fashioned seats, and each of these bars The bars B B are secured to these lug-like portions (1 a by small bolts f, but in such a manner that the parts, though securely coupled together, are not rigidly attached, but permit of a slight rocking motion of each of the bars B upon its supporting-lugs a a.

The mode adopted for carrying out this part or feature of. the structure and invention is most clearly illustrated at Fig. 5,,where it will be observed that the cavity in theunder side of the arm B and the upper surface of the portion a, fitting-into said cavity or seat, are curved, so as to permit these parts to oscillate slightly upon each other at their surfaces of contact, the bolts f fitting so loosely in the holes made for their accommodation in the bar B as not to prevent this slight movement of the parts. I y

As illustrated at Fig. 5, when the seat-bars F may be sprung or depressed in the middle,

they, together with the metal bars B, will be.

thrown out of level, as seen, while the end frames A remain fixed, and no disruptive strain is brought upon the screws or other means of attachment of the bars F to the metal portions B B.

It will be understood that by simply remov in g the four bolts f the set of seat-bars F, with their attached metal bars B B, maybe re moved from the cast-iron end frames, and that by the removal then from said end frames of as new, and desire to secure by Letters Pat= ent, is-- I l The combination of bottom slats F and bars B, having curved socket and slotted; lugs on In witness whereof I have hereunto set my their under side, with legs A, having their hand this 21st day of August, 1878.

upper ends, a, rounded to fit said sockets, and

bolts f, which pass horizontally through said RICHARD W. HOW. upper ends, a", andsaid slots, said bolts and slots being of such relative size and shape as In presence ofto allow the motion of slats F and bars B un- WM. G. HOSEA,
